APPARATUS FOR FILLING CAPSULES.

SPECIFICATION forming part of Letters Patent No. 255,680, dated March 28, 1882.

Application filed September 29, 1881.

To all whom it may concern Be it known that I, JOHANN SCHMIDT, of the city ofNuremberg, in the Kingdom of Bavaria and Empire of Germany, have invented acertain new and useful Improvement in Apparatus for Filling Capsules, of which the following is a specification.

This invention relates to devices for enwrapping medicine so as to be swallowed without experiencing the offensive taste of the same; and it is my object to produce a simple apparatus by which the medicine may be iuclosed other moisture-absorbin g and elastic material;

Fig. 3, a plan view of a plate of rubber that is perforated for supporting a series of concave wafers on their edges 5 and Fig. 4, a sectional view of the rubber plate with a ready-formed capsule placed thereon, and with the stamp in position for disengaging the wafer that forms the upper half of the capsule.

Like letters represent corresponding parts in all the figures.

A denotes thestarnp, which is secured to the shank a of a knob, b. The shank a of the knob is surrounded by a sleeve, B, and the hole in said sleeve through which the shank a is passed is counterbored for forming an annular chamber around said shank that will admit of a coil-spring, d, which surrounds said shank and presses the knob b upward in said sleeve.

Into the bottom face of sleeve 13, and near the exterior edge of the same, are secured three (more or less) pointed wires, g, that project through corresponding holes in plunger A near the periphery of the same, and the bottom face of said stamp A is concaved to correspond with the shape of the wafers 6.

D is aplate, of rubber or other elastic mate- (No model.)

rial, having a series of ci rcular holes, f, punched therein, which are sufficiently smaller in diameter than the wafers, each of said holes being intended for receiving and holding one of these wafers while they are filled with powdered medicine. For this purpose these wafers 0 are made concave at one side and convex at the other, with a straight flange or edge, so as to somewhat resemble a miniature soup-plate in shape, and they are composed of a paste of flour that is pressed and baked between heated molds.

E isa shallow box or pan that contains a pad of hair, felt, or other absorbent, and which is to be soaked with water.

For making capsules I place as many wafers as capsules are desired, with their concaved sides up, in as many holes in rubber plate D, and fill each with the required amount of powdered medicine. Then I place the same number of wafers with their convex side up on a piece of thick pasteboard. Now I grasp the sleeve B of stamp A with the hand and pick up one of the wafers on the pasteboard by spring at is compressed and the points 9 are retracted into the stamp A, when the capsule will a drop off.

The wires 9 are provided near their points with a small annular groove for better holding the wafer e.

Heretofore gelatine capsules have been in general use, which, however, will not always dissolve in a sick stomach, while flour-paste wafers will be dissolved without difficulty by simply becoming moist.

As will be noticed,the method and apparatus above described for making capsules is very simple, and will be desirable for every family.
